UNITED STATES PATENT OFFICE.

JOSEPH W. WEISS, OF BALTIMORE, MARYLAND.

COLLAPSIBLE OR KNOCKDOWN BOX.

7 i; all whom it may concern:

Be it known that I, Josnrn W. \Vmss, a citizen of the United States, anda resident of Baltimore, in the State of Maryland, have invented certainnew and useful Improveknocking about which these boxes undergo whenshipped from point to point wit-h articles of merchandise packedtherein.

I urtherobjects and advantages will appear from the detailed descriptionand particularly pointed out in the claims.

Collapsible or knock-down boxes have come into vogue by reason of theiradvantageous characteristic in taking up little room when in collapsedor knockdown condition, so that a great many may be kept on hand. storedand used "from time to time as occasion requires. Hitherto, however,boxes of this description have been limited in their capacity as to theweight of the articles to be packed therein by reason of their flimsyconstruction and their inability to stand rough handling during thecourse oi shipment or transportation. Railroad companies have beenaccustomed to place a limit on the permissible weight of material whichmay be transported in each box owing to the flimsiness in constructionwhich endangers the bursting of a box or its mutilation. when roughlyhandled while containing more than a certain weight of material.

When devising means for strengthening these boxes, it is necessary tobear in mind that boxes of this description must be light and cheap;otherwise their cost and added expense in transportation wouldmaterially detract from the other advantages. I have,

therefore, provided a collapsible box or slotted carton in which thematerial of the box itself is so disposed and formed that a maximum ofstrength and rigidity is ob tained. y

In making the box, I form the blank with two or more folds whichincrease the strength of material and the stiffness and rigidity just atthe points which receive most Specification of Letters Patent.

of the impact incident. to the knocking about and rough handling of thebox. In one of the forms of my invention these folds are disposed at theend edges of the box a lja cent to the flaps. This results in the endsof the box being not only strengthened but also formed with lateralprojections which protect the body of the box from impact. 'llheseprojections receive any blow which the box may receive in dropping or inbeing struck by anexternal object and also space the body from thesupporting surface, so that the weight of another body resting on thesame is borne by these end projections which are also reinforced by theflaps constituting the lid of the box. In some cases, I prefer to insertmetallic corner pieces Within the folds at the corners which as a rulebear the brunt of the knocks. These metallic pieces may be kept separatewhen the boxes are collapsed and readily inserted when they are set up.In other cases, I prefor to embed a wire, metal strip or nonmetallicstring or tape within the folds to further strengthen the ends of thebox and to 't'.-u'ilitatc the sealing of the same. In other forms o't'my invention additional transverse folds'may be formed in the body ofthe box or longitudinal folds may be formed on the longitudinal edges orintermediate. portions of the body of the box.

In the accompanying drawings, Figure l is a perspective viewillustrating one form of my invention with the folds situated at the endedges oi the box. Fig. 2 illustrates the carton partly collapsed. Fig. 3is a tragmcntal side view illustrating the folds as extending furtherdown the body of the box so as to reinforce it for a greater length.

Fig. 1- is a fragmental section and Fig. 5 is a perspective view of aform in which the flaps are made separate from the body and are formedin one piece at each end, making a three part construction for theentire carton. Fig. *6 is a tragmental section of an other form of threepart construction. the fold being" made in the flap instead of the body..Fig. 7 is a fragmental section illustrating another form in which thefold is partly in the body and partly in the flap. Fig. 8 is a sectionillustrating a metal reinforcement used at the corners. Fig. 9 is aperspective View illustrating the angle piece threaded through the foldto reinforce the ends of the box. Fig 11 is a perspective viewillustrating a preferred form of metal reinforcement; to be used at thecorners. Fig. 12 is a perspective view illustrating a modified formhaving transverse folds in the body of the box. Figs. 13 and 14 areperspective views illustrating modifications with longitudinal folds atthe edges and, in termediate portions of the sides of the box.

Referring to Figs. 1 and 2, the carton is formed of a blank which isscored longitu'dt nally so as to readily form its longitudinal sides 1,2, etc., and also scored on lines adjacent to its ends. The ends arethen slitted so as to form flaps 3, 4, 5 and 6, each containing sections7 and'8 formed by the scoring. The latter are then, folded over into anS shaped fold and attached to the sides 1. 2 etc. in any desired manneras by staat the box and further strengtheningthe same.

pics 9. The meeting edges of sides 1 and 2 are then united by a strip 10of canvas or other suitable flexible material which is pasted, glued orotherwise attached thereto. The box is then complete and ready forshipment in knock-down condition. When it is desired to set it up, theedges 11 and 12 on the sides 1 and 2 are compressed inwardly so as togive the box. its rectangular shape whereupon the flaps 3 and 4 areturned over and flaps 5 and 6 are also turned over so as to lie on topof the flaps 3 and 4c. The contiguo1.1s.faces of the flaps may be gummedor have other attaching means thereon to firmly secure them to eachother and close the ends of the box. When one end is thus closed, thearticles to be packed are inserted in the box, the other end of the boxis similarly closed and it is then ready for shipment. In some caseswhen it is desirable to still further strengthen the box, I may insertpreferably metallic corner strengthening pieces such as illustrated inFig. 11, the same consisting of a bracketdike construction havingangularly disposed sides'13 Fig. 11.) I have indicated these anglepieces in dotted lines in Fig. 1.

In Fig. 3, a construction is shown wherein the sections 7 and 8*,corresponding to sections 7 and 8 in Figs. 1 and 2, are extendeddownward further so as to strengthen the ing the sides l gaand 2", etc.separate from the top and bottom pieces containing flaps 3 4", 5 and 6The section 7? is integral with the body of the box while. thesection 8'is integral with the flap portion; I This section '8" extends all theway around th bqx and conceals the raw meeting edges'of-the section 7thus adding to the appearance of pering with the contents of the box.

is designed. and 14 and a uniting top portion 15. (See' noose la I Inthe construction illustrated in'Fi 6, the end pieces contain the foldedsections while the body of the box is not folded. The fold consists ofsections 7 and 8. extending around the box and having the flaps 3, a",etc. integral therewith,

In Fig. 7, I have illustrated a form in which the inner section of thefold is formed of two parts, one of which 7 is formed integral with thebody of the box, While the assembled in place when the boxes are set up.(See Fig. 8.)

In Fig. 10, I have illustrated a wire or tape 17 inserted at the bottomof the fold and extending all around the box so as to further strengthenthe ends. This wire or tape may be inserted within the folds before theyare attached together and may be permanently held therein, and ifdesired, the ends of the wire or tape may be fastened with a seal 17 ato prevent unauthorized talrln- T is is especially eflicacious in boxeshaving the intermediate fold such as illustrated in Fig. 12 hereinafterdescribed.

In Fig. 12, I have illustrated a form in which transverse folds 18 areformed also in the body of;the box intermediate the ends so astof-ui'ther strengthen the box at intermediatepoints. If desired, thesefolds maybe multiplied to any required number according to the purposeforvvhich the box In Fig. 13 a form of construction is illustratedwherein the folds 19 are formed at' the longitudinal edges instead of atthe end edges of the box. In this form of construction the fold ispreferably formed on each side of a longitudinal edge forming a double 8as clearly shown in this figure. The material may, if desired, be cutaway during the formation of the blank or at any time thereafter so asto leave the flaps free from the fold.

In Fig. 14 a' form is illustrated with longitudinal double Sshap'edfolds 20 located at or near the middle of the longitudinal sides. Theouter flaps 5 and 6 are preferably shortened so as to abut the fold orridge extending on the inner flaps 3 and 4 the fold on the flaps thusforming a cross or strengthening spider materially increasing thestrength of the ends of the box.

It will thus be seen that I have provided a collapsible box or cartonwhich is strong and durable and is capable of withstanding considerablerough handling. However, the cost of manufacturing these boxes is notappreciably increased as the result is produced principally by theproper disposition of the strengthening strip may very readily be Tembedded or attached Within the folds at a slight additional expense incost of ma terial and manufacture and thus further strengthening, thebox. i

It will be noted that in all of the forms I have disclosed, the boxrests on its reinforced edges causing the latter to-receive the bulk ofthe weight and impact and thus protecting the comparatively weak bodyportion of the box.

Various modifications may be made within the skill of a mechanic withoutdeparting from the spirit and scope of the invention as defined in theclaims.
